Quisling

quisling

\KWIZ-ling\ , noun;

1.

Someone who collaborates with an enemy occupying his or her country; a traitor.

Urban dictionary says: During a Zombie-pocalypse a quisling is any person who has become so physiologically disturbed that he/she subconsciously convinces him or herself that they are one of the walking dead. A quisling will imitate a zombie perfectly and will attempt to feed on a normal human should it encounter one. A quisling's bite is NOT infectious. Because a quisling is not truly one of the undead, a quisling can be killed like a normal human, not just with a head shot.
